Give your Godzilla V8 a Kooks exhaust upgrade

Pair your 7.3-litre Godzilla engine with stainless long tube headers and H.O. GREEN catted connections. This Kooks kit joins the OEM exhaust on the supported 2020-2022 F-250 and F-350, with the fitting hardware included so you can plan the front exhaust conversion as one package.

SKU: 1400H640

Headers, front pipes and hardware together

The 304 stainless headers feed matching H.O. GREEN catted pipework with an OEM rear connection. That lets you keep a rear exhaust using the factory interface while replacing the manifolds and front connections together.

For your 7.3-litre petrol Super Duty

This is the Godzilla petrol V8 application. Choose it against the exact F-250 or F-350 year and trim listed below, and have the installation and calibration planned around any other engine modifications.

Tuning for your exhaust upgrade

We recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. Contact us to discuss the right tuning route for your vehicle.
